I prefer the boxer briefs
They do not provide enough support. They lack fabric where it is needed. Was worth a try. Tighty whities would probably be better in terms of fit.

I’m 5’11”, 165 lbs and ordered medium and I think small would fit me a little better. Cool and lightweight. No itch from the merino wool.

Looks good but it's flimsy
Used when traveling in warm climates, washing every day, it is better than cotton but flimsy and the fabric is already transparent in between legs. Also very expensive.

Best underwear Ever!
[This review was collected as part of a promotion.] I wear my merino briefs and previously purchased boxers daily. They are comfortable and never pick up any odor. I have thrown away my cotton underwear!

I don't know how they always seem to stay fresh
[This review was collected as part of a promotion.] My fave underwear. A little bit low profile on the sides, but that's also great for it staying cool and ventilated. Can get away with more then one wear on really long trips, which is probably their best features.

The only underwear I ever buy
[This review was collected as part of a promotion.] I've been purchasing IB for 10 years and these are the only briefs I wear. I still love the design and fit!

Great for travel
[This review was collected as part of a promotion.] Super comfortable and fast-drying. I like packing light, and with these I can pack just a few pair while traveling, wash in a sink, hang to dry and in a few hours they're as good as new.

Poor design, not enough material
Not sure who designed these but pretty sure it wasn't male. The width of the crotch area is far too narrow. This causes the male parts of my body to slip out, usually on one side or the other. Very uncomfortable. When I measured the width, it was about 2 inches. When I measure the crotch width of other brands of briefs I own, it's 4 inches. I noticed at least one other one star review where the person had the same issue I do. I certainly can't recommend this product, although I own and like a lot of other icebreaker clothing.
